我报告的数值程序，它可以用来计算任何红外安全的三喷流观察到的电子-正电子湮灭的次-次-领先的顺序在强耦合常数α（s）。将结果与另一组最近的计算结果进行比较。讨论并解释了三种颜色因子的数值差异。
I report on a numerical program, which can be used to calculate any infrared safe three-jet observable in electron-positron annihilation to next-to-next-to-leading order in the strong coupling constant alpha(s). The results are compared to a recent calculation by another group. Numerical differences in three color factors are discussed and explained.
